With a view of fulfilling Rules 12 and 13 of
Chapter XII, Maritime Convention SOLAS-74, (Compliance with SOLAS
Part XII Reg. 12, MSC145(77) UISC180, RS Rules) that require all
bulk carriers, irrespective of the year of construction, to be provided
with water level gauges and that regulate a possibility of the ballasting
system use, the Maritime Bureau of Register offers to develop designs
and install all necessary gauges on board ships. The system is certificated
by RS.
The water level signaling system is intended for detecting
water inside ship holds and other spaces to be controlled
on bulk ships carrying any kinds of cargo, including dangerous
cargo.
|
Water is detected by means of level gauges based on
seawater conductivity. The gauges are protected to IP 68,
spark-protected in accordance with Exia IIBT6, made for
climatic version OM5 as per GOST 15-150 and are intended
for installation in holds and other protected spaces with
a view of detecting water.
|
A control panel is designed to give visual and audible signals in
case water has been detected and is installed on the navigating
bridge of the ship. The panel provides for warning light and audible
alarms and comes complete with the remote signaling unit. Signaling
is accomplished due to a reserve power supply source (if the main
power supply is not available) and cab be checked by means of an
in-built device that is activated by depressing the pushbutton "TEST".
The panel
is powered from: |
- the main a.c. power supply source 110V, 50-60 Hz:
- the emergency d.c. storage batteries 24 V ±10%.
|
The
signaling panel is protected to IP54 and spark-protected
in the gauge power supply circuits [Exia] IIBX |
Audible
signaling can be disconnected by depressing the pushbutton
"QUIT" on the signaling panel which also has an
output to the external signaling system through the normally
open contacts of the switch. |
